You're welcome Paola :)
I refound a very sweet video from 1989, I wish I could share it with you, but my internet connection is not good enough for that, so I made some screencaps. Beatrice waved, tried to touch the people around her, laughed a lot, so sweet!!
The last pic is one of Sarah, also included in that video - just to compare..:)

The first pic is a screencap, it's a pic of Sarah's own collection she showed at an interview for RTL, on the third pic you can see Eugenie curtseying as her grandmother passed in her coach and on the last pic the car seems to be a bit crowded

You are most welcome, corazon and Romy :)
As to your question: the bride is not related to Sarah, she was Beatrice's teacher at Upton House and is called Helen Webb - or was called so before she married Nicholas Oliver

Iceflower, thank you so much for answering my question!! So I was totally wrong with what I thought..:p I hope you don't mind, I have one more question: who is that little girl with the curly hair, I remember several other pics with her, but never read about her?!

Of course I don't mind, Romy, ask as many questions as you like!! :)
The little girl is called Zenouska Mowatt, she was born in 1990 just like Eugenie, and she's the daughter of Marina Ogilvy and Paul Mowatt and granddaughter of Princess Alexandra, The Honourable Lady Ogilvy.

Eugenie, I do have some short videos, but my internet connection is too bad to upload them, I'm sorry...

Great, Iceflower! You are not only a great source for pics, but also for information! Thank you! :) :) Unfortunately I do only have a few pics :(, I concentrated more on Diana in those years. But I found this one also with Zenouska:
